Some 5,000 traffic policemen and 1,200 Road Transport Department officers would be deployed for the Ops Sikap X11 massive operation to book traffic offenders during the period, he told reporters Tuesday.

Chan said commercial vehicles would be barred from plying the road on Feb 16 and 17 and on Feb 24 and 25 to ease traffic congestion during the peak period.

As was enforced during Ops Sikap X1, he said, the speed limit for federal and state roads would be reduced by 10 kilometres, bringing it to 80kph during the campaign duration.

The Public Works Department would carry out road repairs only for critical jobs during the festive period, he said.
